A Michael Jackson memorial is opening today

A plaque honouring the late `Thriller` singer will be unveiled at the Lyric Theatre in London`s West End, the day before the first anniversary of the singer`s death on June 25.

According to BBC News, the theatrical centre - which is currently showing `Thriller Live!`, a musical based around Michael`s music and life - will hold the special service with the cast of the show performing `Speechless`. The song was originally recorded by Michael and will be released later this month in aid of War Child.

Adrian Grant - executive director of `Thriller Live!` - said: "The sentiment behind the song, and what it now means to me in Michael`s passing, truly reflects the emotions one feels due to his loss - those of sadness, but also remembering the joy he gave the world as we celebrate his life."

Last year`s `Britain`s Got Talent` winners Diversity are expected to attend the event, as they were signed up to support the `Billie Jean` singer for 10 nights of his 50 date `This Is It` tour - which was due to run at London`s O2 arena last year.

MichaelJackson died following an acute Propofol intoxication at his home in Los Angeles on June 25 last year. Dr Conrad Murray found the singer unconscious in his room. He was later pronounced dead at UCLA Medical Centre.
